The custom dashboard at fusion_plating_portal was rendering a 6-card
view at /my/home, but a method-name mismatch left the parent
portal.CustomerPortal.home() route active instead. Rename the
override to home() so Python MRO does the override naturally, and
add CLAUDE.md Critical Rule 16 documenting the gotcha so future
controller-override work doesn't trip on it.
Version bump: 19.0.2.2.0 -> 19.0.2.3.0.
